She is hoping for the best, even though her sister has been gone for nearly four days. Investigators are releasing new details in the search for Susana DeJesus.

"Tootie I miss you, I love you. I want you home. I need you. I miss our conversations. I need for her to come home. That's all that I want," said sister Guilly Puente.

While Puente tearfully pleaded for her sister's safe return, she refused to comment on investigator's suspicions that the armed abductor targeted her sister.

"Right now, my main concern is to get her home and to bring her home safe. That's my main concern. That's the only thing that I'm worried about right now," said Puente.

Susana DeJesus was taken at gunpoint Monday night from outside the Pearland store where she worked. The most solid piece of evidence investigators have is an ATM surveillance photo of the masked gunman in DeJesus' vehicle.

"I cannot say she knew the person who took her. There may have been issues in her life that caused her concern," said Capt. Chris Kincheloe of the Brazoria County Sheriff's Office.

Questions about DeJesus' demeanor the night she was abducted are being raised after the release of a chilling 911 call. The co-worker who witnessed the crime had her son make the call because she was too scared.

"Today they just happened to start talking and this woman (DeJesus) seemed very, very nervous all day," said the 911 caller.

Even though authorities think DeJesus may have been targeted, residents aren't ready to let their guard down.

"It really doesn't make much of a difference it's still a problem and it'' still kind of scary to go around shopping," said resident Ruby Jimenez.

Investigators told us they will be talking to DeJesus' friends in the hopes of learning more about her personal history. They are still asking for the public's help.
